Since 1984, 4B Components Ltd. has been serving the material handling and electronic

component needs of the elevator and conveyor markets in the United States. However, ourroots started over 127 years ago in the United Kingdom when our parent company, BraimeHoldings P.L.C., began producing small pressings with a fly press in 1888.In 1909, Braime introduced the first seamlesssteel elevator bucket, which expanded theirproduct line and their expertise in metalpressings. By 1911, the business had grownto such an extent that a new factory wasopened in Leeds, UK. This facility is still inexistence today and continues to producemetal pressings, including our current line ofpressed steel elevator buckets, and bucketbolts.

In 1971, Braime formed a new subsidiary, 4B Elevator Components

Limited. 4B, an acronym for Better Buckets, Belts and Bolts, wasfounded to specifically serve the material handling needs of theelevator and conveyor markets.

With growing safety concerns and a need to

monitor the performance of bucket elevatorsand conveyors, 4B saw an opportunity to expand into electronic sensorsand controls. By 1984, 4B had developed a complete line of electronicsproducts for monitoring bucket elevators and conveyors.

4B HIGH EFFICIENCY Elevator Buckets

HEIGH

FFICIENCY

At 4B, our basis has always been engineering and our expertise in providingcomprehensive solutions. In keeping with these core values, we designedour family of High Efficiency elevator buckets to deliver the maximumpossible elevator leg throughput for the lowest cost per ton or bushel.Every bucket in every line of the High Efficiency family has five distinctfeatures, each of which conveys efficiency. Only 4B High Efficiency elevatorbuckets have all five features.

MODERN HIGH EFFICIENCY DESIGN

2. WING-LESS SIDE WALLS

Wing-less side walls maximizethe most efficient use and cost ofmaterials.

3. CLOSER SPACINGThe ability to be mounted extremelyclose together provides the mostefficient use of vertical space on thebelt.

TRADITIONAL DESIGNOther designs have angled breakswhich provide no benefit to dischargeefficiency. These breaks merelycopy a feature from the first sheetmetal buckets introduced in the1920s.

Other buckets have a wing or ear

on both sides which adds cost andweight, while offering no functionalbenefit.

Other buckets are too deep to be

mounted closely together or must bemodified from their standard design,adding to the cost.

4. TAPERED BOTTOMSTapered bottoms allow the bucketsto fill and discharge with maximumefficiency over higher speeds.They also create a low diggingfactor which means less materialresistance & degradation and fewerforces on the bucket system.

The vertical sides, wings and

perpendicular bottoms of otherbuckets impede the flow of materialsinto and out of the bucket.

Nesting is not possible with other

bucket designs. More packingmaterials and space are required forthese buckets.

GB SpidexAgricultural & Industrial BucketsGB Spidex Unique Design FeaturesWith the GB system, buckets are centered at very close spacing with a series of buckets without bottoms followed by aclosed bottom bucket. The material is lifted in a continuous column, so the carrying space between conventional bucketsis fully utilized by material to achieve much greater capacity. The buckets fan out as they pass over the head and tailpulleys to facilitate pick up or discharge.The system increases capacity of an existing elevator leg at a much lower cost than the purchase of a new bucketelevator. The GB system can also be used in new elevators to give the same capacity as larger elevators using traditionalbuckets, saving manufacturing costs and plant space.GB Spidex buckets are particularly useful with sticky products which can clog up the bottoms of conventional bucketsreducing capacity and increasing maintenance. With GB buckets, only the bucket with the bottom can become clogged,and capacity can be rated to allow for this. The remaining buckets, being bottomless, are self cleaning. Dense orextremly light materials are also handled easily as GB buckets have the ultimate vented design.Whether your leg is handling grain, feed, meals, fertilizer, or industrial materials such as free flowing cement, 4B candesign a GB Spidex bucket system to deliver the capacity you require.

Elevator Bucket Bolts,

Nuts, Washers & Spacers

4B #1 NorwayElevator Bolts#1 Norway elevator bolts are the most common style used in the U.S. grain industry. The square shoulderunder the flat head of the Norway bolt helps prevent spinning during installation (square peg in a roundhole principle). 4B #1 Norway bolts meet or exceed Grade 2 standards for load, yield and tensile strength.Material

- Nylon insert lock nuts not recommended for #1 Norway bolts

4B FangedElevator BoltsThe fanged elevator bolt is characterized by two sharp teeth that are intended to penetrate the carcassof the elevator belt. Once the teeth penetrate the belt, they help keep the bolt from spinning which easilyallows the lock nut to be tightened.Material

Zinc plated steel or

stainless steel (302)

Features

Unique design - fangs lock bolt in place as nut is tightened

Large bolt head diameter resists belt pull though Extensively tested and used in U.S. grain industry For recessed and flat back elevator bucket holes Bolt torque rating dependent on bucket & belt size Meets or exceeds industry standards for Grade 2 boltsPart Number

4B EasifitElevator BoltsThe Easifit bolt is unique in that it employs a hexagon tip. Special installation tools lock onto the hexagontip to keep the bolt from spinning as the lock nut is being tightened. This varies from fanged or squareshoulder designs that have to bite into the belt to keep from rotating during nut installation.Easifit bolts are especially useful for repair jobs where only the elevator buckets and not the belt are beingreplaced. In this case, reaching around to the back of the belt and inserting replacement bolts can becumbersome. Easifit bolts eliminate the problem of elongated bolt holes that can no longer accept thesquare shoulders of other bolt styles, and there are no fangs to set. Once the replacement Easifit bolt isinserted through the belt and bucket, the entire fastening operation can be quickly and easily finished frominside the elevator bucket.Material

4B Euro DIN 15237

Elevator BoltsEuro DIN 15237 elevator bolts have a concave head and two lugs on the underside to help prevent rotationwhen tightening. Popular throughout Europe for the last 30 years, this fastening system is intended forthe attachment of pressed steel elevator buckets incorporating recessed bolt holes. The recessed areasurrounding the bolt hole is intended to accommodate the similarly domed surface under the bolt head.Because of this domed area under the bolt head, these bolts are not recommended for flat back plasticbuckets, especially on thinner belts.Material

4B Vise SpliceNon-Ferrous(MBG2-AB)4B Vise SpliceFerrous(MBG2)

4B Vise Splices are mechanical splices for use on most

PVC and rubber elevator belts. Each splice unit is madeof three pieces. The outside plates have two differentgripping areas. The ribbed gripping area is mountedtowards the face of the belt. The opposite end has a seriesof both longitudinal and axial teeth. The center plate issymmetrical and cannot be improperly installed around itselongated center hole.The splice functions by using the tension supplied bythe belting. This tension on the belt ends pulls the outerplates apart, and forces gripping pressure towards theteeth on the splice unit. The greater the belt tension,the more pressure is exerted on the gripping teeth at theforward end of the splice.

Mechanical clamping device with a simple three piece construction

Use on PVC and rubber belting Use 1/2 x 4-1/2 long bolts for belts between 1/4 and 1/2 thick Use 9/16 x 5 long bolts for belts between 1/2 and 3/4 thick Maximum operating temperatures: Non-Ferrous 500F, Ferrous 600F Each splice set accommodates two inches of belt width

4B Polysur Steel Web Core Belting

The 4B Polysur steel web core belt is a rubber elevator belt with a special steel cord core. The cords provide lowelongation with high elasticity in the length, and cross rigidity in the width. The built-in elasticity allows runningover slightly crowned pulleys which greatly improves belt tracking, and helps to avoid belt wandering which is oftenthe reason for elevators shutting down. The rigid weft cords act as a barrier to ripping and tearing which increasesthe holding ability for the bucket bolts. This produces a good cross rigid belt resulting in excellent straight trackingcharacteristics.In contrast, most conventional steel cable belts lack elasticity and consequently have to run over truly flat, cylindricalpulleys which increases the risk of belts off-tracking.The 4B Polysur steel web core belt is designed for heavy duty/industrial bucket elevator applications with longcentre distances that require stable running and reliable belts with high safety factors. All 4B Polysur steel webcore belts are manufactured in accordance with DIN 22102 and ISO norms.

4B HIGH EFFICIENCY Elevator Buckets

HEIGH

FFICIENCY

At 4B, our basis has always been engineering and our expertise in providingcomprehensive solutions. In keeping with these core values, we designedour family of High Efficiency elevator buckets to deliver the maximumpossible elevator leg throughput for the lowest cost per ton or bushel.Every bucket in every line of the High Efficiency family has five distinctfeatures, each of which conveys efficiency. Only 4B High Efficiency elevatorbuckets have all five features.

MODERN HIGH EFFICIENCY DESIGN

2. WING-LESS SIDE WALLS

Wing-less side walls maximizethe most efficient use and cost ofmaterials.

3. CLOSER SPACINGThe ability to be mounted extremelyclose together provides the mostefficient use of vertical space on thebelt.

TRADITIONAL DESIGNOther designs have angled breakswhich provide no benefit to dischargeefficiency. These breaks merelycopy a feature from the first sheetmetal buckets introduced in the1920s.

Other buckets have a wing or ear

on both sides which adds cost andweight, while offering no functionalbenefit.

Other buckets are too deep to be

mounted closely together or must bemodified from their standard design,adding to the cost.

4. TAPERED BOTTOMSTapered bottoms allow the bucketsto fill and discharge with maximumefficiency over higher speeds.They also create a low diggingfactor which means less materialresistance & degradation and fewerforces on the bucket system.

Engineering & Design

Bucket Venting, Wear & Reinforcing BandsBUCKET VENTING When elevating fluffy or powdery materials, vent holes in the bottom of the elevator bucket allow material to fill and discharge more efficiently. Asmaterial enters the bucket, it encounters a pillow of air resting in the bottom. Vent holes provide an escape path for this pillow of air, so that the enteringmaterial does not bounce out of the bucket and back down the elevator leg casing. Upon discharge, the vent holes allow air to re-enter the bucket asthe material exits, releasing any vacuum that might be trapped inside the bucket, creating down legging.WEAR BANDS Wear bands, either from mild steel or AR (abrasion resistant) steel extend the life of the bucket by adding additional thickness to the wear surface.This is especially helpful when elevating abrasive materials.

Bucket / Pulley Relative Speeds

This chart is designed for use as a guide to handling free flowing granular materials. For other types of material,please contact 4B.Please note that centrifugal discharge can be at minimum bucket spacing. However, gravity discharge often requiresan increase in bucket space to suit the discharge angle. For questions regarding this, please contact 4B.Centrifugal DischargePulley Diameter (in.)

Drag Conveyor Chain

Get Your Conveyor on Victory Lane!

Proven PerformanceCHS handles several commodities (wheat, durum, soybeans),and will load out about 70,000,000 bushels a year.We have several drag conveyors which use a forged steel chainwith a typical pin and circlip assembly. While this is a goodand reliable method, it can be very time consuming whenchanging out bent or broken chain flights.In November of 2006 we installed a test section of 4Bs newBolt N Go chain and I am quite pleased with the results. TheBolt N Go chain is very easy and fast to install and maintain,as you eliminate the need to separate the chain each time whileinstalling a new flight. Also there is no need to slacken off thechain or re-tension while changing flights. This alone will saveuntold hours on the routine maintenance of these conveyors.As our old chain wears out I will definitely replace it with 4BsBolt N Go chain.Bill Hoffer - Head of MaintenanceCHS Inc.
